If you look in the foreground , you can see that 3 shells are next to each other and then there is space for next 3 shells deep row. so there are paths from left to right of the photo that you can walk between the shells

they are inspecting serial numbers, as everyone knows a bomb or shell won't work without the correct serial number printed on it.
A couple more shell manufacturing pics. WWI. Largest size images available.

šI bet the slick tires on the front of that one on the left really help with tractionš
Depending on conditions, they give the ultimate in traction. Have a look at Formula One wheels.
I would love to see one up close, and maybe even crawl under it to scope out the many years gone by, engineering! What brutes they must of been to drive in those years, with not even so much as power anything except maybe the dump box! It would nearly wear a guy out just getting up and down from these beast's, but then after all, they were not use to many fancy, work saving add on's such as automatic transmission's, power steering and brakes! I'll bet they were the true meaning of a stiff, rough ride!
Try as I might, have other tasks this evening, can't produce legit references/ justification for ordnance serials.
Large naval gun barrels have a predetermined lifespan, even with chromium plating in the first ~2/3rds of length. The hygroscopic nature of black powder causes erosion, combined with the heat and friction produced in firing. Compensating for bore erosion is incremental sizing, as projectiles were 'custom' lots, made suitable for a particular ship, and more specifically condition of bores.

Occasionally, the used micrometers appear on auction sites. The frames are near fully rubber insulated to guard expansion when held in the hand. When in the market for larger micrometer's with tenths [10,000] verniers, these are a good choice.
